You’ll find out how Level-to-Level Tunneling Protocol (PPTP) encapsulates Level-to-Level (PPP) frames into IP datagrams for transmission over an IP-based network. They have been initially designed to transport circuit mode communications from a wide range of completely different sources, primarily to assist actual-time, uncompressed, circuit-switched voice encoded in PCM (Pulse-Code Modulation) format.
